Engine Vibration

[pellom@YorkU.CA (Sal Guzzo)]

Well, the 2.0l 8V 3A block swap is complete and running.  I still need to
wire up the full throttle switch to the O2 box but otherwise it's running.
Thanks to all for the enormous help.

The last problem I need to sort out prior to beating on the crap out of it
deals with this annoying vibration which seems to be emitted by the motor.
I did install a lightened flywheel but it was not balanced.  Before me
ripping this motor apart I need confirmation that the flywheel can cause
this sort of thing.  Any ideas?
